The piece being installed Friday - known as the 'grillage' for the grill-like appearance of a portion of the section - is considered the most complicated installation of the entire tower project, according to Caltrans.
KCBS' Holly Quan Reports:
The placement of the fifth section of the self-anchored suspension tower will bring the tower height up to 495 feet, whereas before Friday, the tower stood at 480 feet.
Construction of the first tower section began last July, with the second following in October, the third in December and the fourth just last month.
Caltrans officials said the $6.3 billion project to build the new eastern span and make the entire Bay Bridge more seismically safe is still on time and is slated to be finished in 2013.
